Subject: [PATCH 00/15] arm64: KVM: add SPE profiling support for guest

Hi,

This series implements support for allowing KVM guests to use the Arm
Statistical Profiling Extension (SPE).

The patches are also available on a branch[1]. The last two extra
patches are for the kvmtool if someone wants to play with it.

Regards,
Sudeep

v1->v2:
	- Rebased on v5.2-rc1
	- Adjusted sysreg_elx_s macros with merged clang build support
